Notes
Dr. Walter Shewhart (Deming and Juran”s teacher of SPC) called these “Chance-Causes. The main point is that Special-Causes may be treated by the individual worker, if they are given information and power, while Common-Causes must be treated by management. W. Edward Deming”s term (“special”) is the preferred term in this book.
